What is GHSA-9Q64-MPXX-87FG?

GHSA-9Q64-MPXX-87FG is a high-severity open redirect vulnerability in ecstatic (npm), affecting versions < 2.2.2. It is fixed in 2.2.2, 3.3.2, 4.1.2. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.

Which versions of ecstatic are affected by GHSA-9Q64-MPXX-87FG?

ecstatic (npm) versions < 2.2.2 is affected.

Is there a fix for GHSA-9Q64-MPXX-87FG?

Yes. GHSA-9Q64-MPXX-87FG is fixed in 2.2.2, 3.3.2, 4.1.2. Upgrade to this version or later.

Is GHSA-9Q64-MPXX-87FG exploitable, and should I be worried?

Whether GHSA-9Q64-MPXX-87FG is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether GHSA-9Q64-MPXX-87FG is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix GHSA-9Q64-MPXX-87FG?

Upgrade: ecstatic to 2.2.2 or later, ecstatic to 3.3.2 or later, ecstatic to 4.1.2 or later.

Summary

Open Redirect in ecstatic

Versions of ecstatic prior to 4.1.2, 3.3.2 or 2.2.2 are vulnerable to Open Redirect. The package fails to validate redirects, allowing attackers to craft requests that result in an HTTP 301 redirect to any other domains.

Impact

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

Affected versions

ecstatic (< 2.2.2) ecstatic (>= 3.0.0, < 3.3.2) ecstatic (>= 4.0.0, < 4.1.2)

Security releases

ecstatic → 2.2.2 (npm) ecstatic → 3.3.2 (npm) ecstatic → 4.1.2 (npm)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
